Phosphoric Acid 85% Solution , – Essential Industrial Acid for Fertilizers, Food & Metal Treatment
We supply high-purity Phosphoric Acid at 85% concentration. This vital inorganic acid serves as a fundamental raw material and processing agent across major global industries. Consequently, manufacturers actively use it to produce phosphate fertilizers, food-grade acidulants, and metal surface treatments. Moreover, its versatile reactivity makes it indispensable for chemical synthesis, water treatment, and electronics manufacturing.
Core Applications for Phosphoric Acid in Industry & Manufacturing
This powerful acid drives production in agriculture, food, and industrial processing. Its roles are diverse, foundational, and high-volume.
First, the agricultural fertilizer industry relies on phosphoric acid 85% as the primary precursor for phosphate fertilizers like DAP and MAP. It provides the essential phosphorus nutrient for global crop production. Therefore, fertilizer plants worldwide depend on it as a cornerstone of their manufacturing process to support food security.
Second, the food and beverage sector utilizes food-grade phosphoric acid as a key acidulant and pH regulator. It imparts a sharp, tangy flavor in cola beverages and acts as a preservative and acidifying agent in jams, cheeses, and processed meats. Furthermore, it is used for equipment sanitation in dairy and food processing plants.
Third, the metal treatment and manufacturing industry employs this industrial acid for pickling, rust removal, and phosphating. It cleans and prepares steel surfaces for painting or coating, creating a corrosion-resistant layer. Additionally, it is crucial in semiconductor etching, water treatment for scale inhibition, and as a catalyst in organic synthesis.
